The Lohan clan has been left livid by a flub on Tuesday night’s installment of the Late Show with David Letterman that resulted in fourteen year old Ali Lohan mistakenly being called Lindsay by host David Letterman. (In David’s defense, we’d just like to point out that the Ali/Lindsay slip-up was an honest mistake. After all, both sisters resemble overtanned baked potatoes.) The aspiring teen singer hit the late night circuit to promote the Lohans new reality series, Living Lohan, debuting Monday, May 26th at 10 p.m on E!

“It’s a sticky area because Ali’s rising star is both enabled and discredited by her sister’s notoriety,” an insider revealed to MSNBC. “Ali doesn’t want to ride Lindsay’s coattails, and Dina has always believed Ali is a great talent in her own right.”

“When he calls her Lindsay, it reminds everyone of how much she emulates her sister’s behavior — she’s basically adopted her voice and look. We can expect it will be hard for Ali to stay out of the tabloids.”
